If you study astrology, how the names got picked start to make more sense. They even correlate to the seven days in Genesis. The thing about astrology is they use pagan names just we still do for the days of the week. Saturn was the god of time, thus governing the end of the weekly cycle. The sun governs the first day of the week -- when we see "light" first appearing.For all intents and purposes, the origin of the days of the week are meaningless. Wednesday was not for a Roman but for a Norse god -- Wodin. As were several others.
